MAKING'COLORED DESIGNS ON WOVEN FABRICS.

" "-",SPECIFIQATION forming part of Letters Patent No. 617,772, dated January 17, 1899. v I I v v v dpplication filed September 27,1897. Serial No, 653,246. (Specimens) Toall whofltzlt may concern.-

- BeFit known that '-I, FRITZ RETTIG, of Mulhouse',.A lsace, German Empire, have inventedcertain new and useful Improvements in .the Production of Colored Designs on Woven Fabrics, of which the following is a specificawork, on a plain ground.

tion. 1

v This inventionhas reference to the production of colored designs on fabrics woven with embroidery-like. patterns.

. For. some years fabrics have been woven-so as'to show raised designs, like embroidery- The said fabrics are made in plain white and sometimes woven in colors, ,the white fabrics being dyed in plain colors, if desired, according to the usual v methods. 1; imitations of fabrics woven in colors have beenproduced by printing so as to show white designs on a colored ground.

This has sheen effected by applying the color onthe backof the material in the form of a thick pasteQso. that. itmay impregnate the ground, but not the raised or embroidered part, the fabric being then dried and fixed in the .usualywayfor example, by steaming.

' Up to the present, however, it has not been found possibleto produce Woven fabrics having embroidery-like designs colored-on the raised portion; and the object of the present invention is the production of such colored fabrics.

In carrying out this invention a woven fabric is taken having thereon an embroiderylike design. This fabric should preferably be entirely white; and the invention consists in applying to the raised design-a different color to that of the ground.

According to one way .of effecting the invention a resist is placed on the back of the color is printed on the other side, which is fixed in the usual manner-fo1example, by

fabric, which is then dried, and then a new steaming. As the resist prevents the color from being fixed in the ground, only the embroidery-like or raised parts of the fabric eventually become colored. By. washing,the

. resist and the unfixed color are re1noved, and

a colored design is thus eifectively' obtained on a White or plain ground. 4 v

Theinvention can also be carried out by the discharge process. In this case the fabric is dyed with the color which it is eventually desired to obtain on the embroidery-like or raised portions. The back is then padded with the discharge and the'fabric then passed through the discharging-bath in the usual way, the result being that the dye is discharged, except that upon the raised portions.

Having stated the nature of the invention, I will further illustrate it by giving the following examples; but I premise that these can be varied in theirdet-ails and that they are merely typical, illustrating the applica tion of the invention to particular cases:

Example 1: The back of the material is padded with thickened acetate of lime, dried,

alizarin colors are padded or printed on the other side, followed by drying, steaming, and washing. I

Example 4: The back is padded with a stannous-salt resist, and then substantive azo colors are padded or printed on the other side, followed by drying, steaming, and washing.

Example 5 After padding the material with fl-naphthol it is dried, padded, or printed on the back with a tin or sulfite resist, as described before, The material is dried,'and then there is padded or printed on the other side a diazo solution.

Example 6: The back is padded with a thickened sulfate-of-zinc solution, and there are then printed on the other side pigment colors thickened by means of albumen.

I will nowproceed to give examples of the manner in which the invention can be carried into practice, using the discharge method, as.

hereinbefore described.

Example 7: The material is dyed withindigo. The back is padded with thickened po-- tassium chromate, dried, and passed through an oxalic -sulfuric -acid bath, washed, and

'- tartar emetic or antimony salt.

"dried. 13y this-means there are obtained blue raised designs on a white ground.

Example 8: The material is padded with tannin solution, which is fixed by means of Then the back is padded with thickened sodium hydrate. The material is then dried, steamed for from one to two minutes, passed through an acid-bath, (hydrochloric or sulfuric acid of 2. to thc Baurn,) washed, tannin colors.

Example 9: The material is mordanted with chrome, iron, or aluminium mordants. The

and dyed with back is padded with a discharging paste,-

(thickened tartaric or citric acid,) steamed for one to two minutes, or aged, passed through chalk and cow-dun g baths, and dyed with alizarin colors.

Example 10: The material is dyed with diiect. 'azo colors. The back is padded with thickened tin-salt discharge, followed by a steaming and washing.

It is possible by this invention to startwith a fabric previously dyed in any single color, the effect beilng that the new colored designs are on a colored ground; but care must be taken that the coloring-matter on the dyed fabric originally taken does not interfere with the action of the resist.

A more practicalmethod of producing colored raised designs on colored grounds is to incorporate in theresist a suitable coloringmatter. For example, the back of the fabric may be padded or printed with a tannin-color resist,-which contains'substantive azo colors, and then dried. The right side of the fabric is then printed or padded with tannin colors,

dried, steamed, and washed. colored raised designs are obtained on a col- In this way ored ground. The same effect can also be obtained by following example 1 and incorporating a coloring-matter with the thickened acetate of lime. In this case a black raised design is obtained on a colored ground.

In carrying out this invention the back of the material may be padded with a resist of such composition and strength as to be only vable to reserve a part of the colors, which are padded or printed on the other side, thus .making more than one color or shade in addition to the ground.

What I claim, and desire to secure by Letters Patent, is-

1 The improved process of producing e1nbroidery-like woven material having a raised and colored portion, which process consists 1n weaving such fabric with a raised design on its face, applying color to the face of the fabric, protecting the back and ground of the fabric from the applied color, fixing the color on the face of the raised portion, and remov-' ing the unfixed color.

2.. The process of coloring embroidery-like.

incorporated therewith a suitable coloringmatter, in then applying an appropriate coloring-matter to the front of the fabric, fixing the color of the ground and that of the raised pattern and removing the resist and unfixed color. I

In witness whereof I have hereunto signed my name in-the presence of two subscribing witnesses.
